Hart's lack of football during the 2017-18 campaign has led to suggestions that the on-loan Manchester City goalkeeper will be dropped from his previous role as number one for the tournament in Russia.
The 30-year-old, however, has said that he is more than prepared to battle for the Three Lions jersey ahead of this summer's competition.
"It's no different to any moment that I've been [playing football]," Hart told reporters. "Even when I was trying to get into my Sunday league team, it was the same script: people want to play football.
"That's no different to the one here. I am not here to answer critics. I am here to play football, enjoy what I do and try and help my team the best way I can."
